2 Claims. (Cl. incl- 274) Itis another object of the invention to provide an attachment to deconcentrate the blast of air from a fan thus practically removing the unhealthy, direct current from the fan; as well as 15 the inconvenience of theair disturbing papers and similar articles within the vicinity of the fan. It is a further feature of this invention to provide a device of the character described whereby the attachment may be applied and removed with ease from an electric fan.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts, and use, an example of which is givenin this specification and illustrated in the accompanying drawing, wherein: l I t Figure 1 shows a front elevation of the attachmentas applied to a fan guard. I L

I Figure 2 shows a front elevation of the deflector so as constructed before attachment to the fan.

Figure 3 shows a side elevation of the current deflectorconnected to the guard of an electric- Referring now more particularly to the draw-.

w ing, wherein like numerals of reference designate the same parts in each of the figures, the numeral 1 designates the cone-shaped current deflector plate which is preferably formed of sheet metal.

[In Figure 2 there is shown the slit 2 in the current deflector. The clips 5 are held tothe margin of the current deflector by the screws 4, said clips having a hook formed at their radially,

. outwardly directed ends as shown more specifl- ,cally in Figure 5. l l l 50 In Figure Bthe current deflector is shown as attached to the fan guard 6 which has an annular wire I around which the clips 5 are attached.

In order to attach the current deflector to the guard one of the wires 8 of the guard 6 is inserted into the slit 2 approximately the full depth of the slit and the deflector is then rotated about the wire 8 into the inside of the guard.

One edge 9of the slit 2 is then placed over the opposite edge Ill of the slit 2 and connected by the screw II, thus forming the cone-shaped deflector.

The deflector is preferably of smaller diameter than the diameter of the blades of the fan so that 10 a portion of the air is permitted to pass over the deflector, while the majority of the air is turned outwardly away from the fan thus deconcentrating the air from said fan. This deflector is not limited touseon an electric fan but may be 16 used on any fan having a suitable guard.

, The deflector may be constructed Without the slit 2 if the deflector is attached to the guard in the process of construction of the guard. In this deflector comprising a fan guard forming a support, a flat circular plate formed of flexible material and having a radial slit to receive a side bar of the fan guard whereby the plate may be inserted into the guard, the margins formed by the slit overlapping, means for securing the overlapped margins together whereby the sheet is held deformed in a substantially conical shape and means on the margin of the deflector for securing the deflector to the fan guard with the margin of the deflector directed forwardly.

2. A current deflector for an electric fan, said deflector comprising, in combination a fan guard, a flat circular plate formed of flexible material and having a radial slit to receive a side bar of the fan guard to facilitate the insertion of'the plate into the guard, the margins formed by the
